I have a reproducible lockup on a Via C3 board (with kernel compiled for
C3).
This kernel has some wireless patches and the slub fix from a few days ago.
Same kernel (compiled for P-II, SMP, pre-empt) works fine on an Atom
system.
Shortly after the login prompt I see this on serial console:
BUG: spinlock lockup on CPU#0, net.hotplug/1899, f5a2c470
I tried enabling lockdep and saw no splats.
I'm not sure why there isn't more of a backtrace...
Nevermind..it printed out a stack trace the next time.
Bug is un-initialized spinlock in ath5k...I sent a patch to the wireless
mailing list...
